It sounds like you are having the same problem I had (I did a how to on this) mine ended up being the brain module in the rear had went nuts

I didn't know mine had failed till my mom asked me why it was throwing out ice cold air when the temp was set to 90(that was NOT FUN) women hate being cold in winter and my mom and grandma was in the back seat and both complained the whole trip
It costed me around 100 for the module and 130 something for the Actuator
